DEVICE FOR INSERTING AND CLlNCHING METALLIC STAPLES.

SPECIFICATION forming part of Letters Patent No. 260,365, dated July 4, 1882.

books, papers, 850., and when driven by a detachable staple-driver, or with one which may sometimes be used separately from any other device for the simple insertion of staples without clinching; and it consists of a clinchinganvil provided with a suitable guidearm containin g a guideway to direct the end or mouth of a staple-driver to a proper position, so that when a staple is driven thereby the points will be directed toward the inclined surfaces of the clinching-anvil and be turned, inward toward each other upon the under side of the work, as will be better understood by reference to the drawings accompanying this specification, in which- Figure 1 is a side view of the base and guide, with sheets upon the former and the stapledriver above them. Fig. 2 is a front view,

partly in section, showing the driver and clincher or anvil in the act of securing the sheets together. Fig. 3 is a plan view of the anvil.

Fig. 4 is a plan viewof the guide and clincher or anvil.

Application filed January 28, 1881. (No model.)

To the rear end of the base 13 is attached a metal blade or arm, A, which projects hori- 5 zontally forward over the clinching-cavity b of the anvil. This arm A is provided at its forward end with a guideway, a a, for receiving and guiding the mouth of a staple-driving punch directly over the clinchin g-cavity. These guideways a a maybe formed in various ways. In Fig. 4 a circular orifice is formed in the end of the guide-arm A,"in which the staple-driver may stand in various positions, as indicated by the dottedlines in said figure, andin which any two opposite points within the circle may form the guideways a a.

It is now obvious that if papers to be bound or other material to be fastened be placed upon the anvil, over the clinching-cavity-b, as at 0, Figs. 1 and 2, and the mouth of a detached staple-driver be introduced within the guideways aa, so that its open end is resting on the work 0, and if a staple be driven from it downward through the work, the ends of the staple will, upon protruding through the under side of the work, impinge on the slanting slides2 2 of the clinching-cavity, and be thereby directed inward toward each other, and thus become clinched, in the manner as shown in Fig. 2.

Having thus described my invention, what I claim as new therein is As an improvementin devices for inserting and clinching metallic staples with detachable staple-drivers, a base provided with a clinching-cavity, combined with an arm extended over said cavity and having above the latter a guideway for receiving and guiding the mouth of the staple-driver to position over the clinching-oavity.

In testimony whereof I affix my. signature in presence of two witnesses.
